Also, please note that the EmuNAND only works on real hardware. There is currently no way to play prototype titles on an emulator.

The dump we originally received appeared to have been modified. The header checksum didn't match. We received another ROM that matched the header checksum, which led us to believe that the ROM we initially received had been modified somehow. There are only 4 bytes different in total.

You may recall we announced that a live stream showcasing new prototypes would be happening sometime in March. We've delayed this stream to April 4th at 3:15 PM UTC.

More details will be announced in the coming days.

This is a prototype of the unreleased Game Boy Color version of 40 Winks! This build has 6 playable levels and 2 playable characters (Ruff and Tumble). It seems to have been from very far along in the game's development.
